Abstract
Description
- The present invention relates to a method of producing filter-tipped cigarettes.
- As described, for example, in British Patent n. 2,241,866, filter-tipped cigarettes are formed on a filter assembly machine, along a first portion of which each portion in a first succession of cigarette portions with a given spacing is joined, at a rolling station and by means of a strip connecting element, to a corresponding portion in a second succession of cigarette portions, to form a tobacco item hereinafter referred to as a "double cigarette". Each double cigarette consists of two cigarette portions separated by a double filter connected integral with the two cigarette portions by said connecting element, the central portion of which surrounds the double filter, and each end portion of which surrounds the end of a respective cigarette portion.
- Again according to the above British patent, once formed, the double cigarettes are fed successively through a cutting station where they are cut transversely in half to form two successions of oppositely-oriented single cigarettes. That is, downstream from the cutting station, the cigarettes in each pair of cigarettes formed by cutting a respective double cigarette are arranged with the respective filters facing and substantially contacting each other.
- According to the above British patent, the two successions of filter-tipped cigarettes are then fed to a turnover station where each cigarette in one succession is turned over and fed into the space between two adjacent cigarettes in the other succession, to form a single succession of equioriented cigarettes, which are then fed to the output of the filter assembly machine and from there to the input of a packing machine.
- It has recently been found necessary to connect the filter assembly machine to a packing assembly consisting of a double packing machine, i.e. with two packing lines, or of a pair of individual packing machines. In other words, the problem has arisen of connecting the filter assembly machine to a packing assembly presenting two inputs a given distance apart.
- One possible solution would be to employ a two-line filter assembly machine of the type described in British Patents n. 2,201,576 and n. 2,202,127, but without the turnover station at the output, which forms the two lines into one. This, however, obviously poses the problem of devising a packing assembly with two inputs capable of receiving respective successions of oppositely-oriented cigarettes.
- Recently, the above problem has been solved using a filter assembly machine whereby, as described in Italian Patent Application n. BO92A000311, two successions of oppositely-oriented cigarettes are fed to a turnover station where the cigarettes in one succession are turned over outwards by 180° in relation to those in the other succession, to form two successions of equioriented, transversely-spaced cigarettes. On the above machine, the cigarettes in the first succession are turned over by means of a turnover unit comprising, for each cigarette, a respective turnover member for receiving and retaining a respective cigarette; and a drive unit common to all the turnover members and which provides for rotating each turnover member 180° about its axis.
- Though they do in fact provide for successfully supplying a packing assembly featuring two inputs a given distance apart, a major drawback of known filter assembly machines of the above type is the relatively high cost involved, mainly due to the large number of components and relatively complex design of the turnover unit.
- It is an object of the present invention to provide a method of simultaneously feeding two successions of equioriented cigarettes to two spaced inputs of a packing assembly, and which at the same time provides for overcoming the aforementioned drawback.
- According to the present invention, there is provided a method of producing filter-tipped cigarettes, the method comprising stages consisting in feeding two side by side successions of oppositely-oriented filter-tipped cigarettes; and turning over the cigarettes in a first of the two successions so that they are oriented the same way as the cigarettes in a second of the two successions; characterized in that said turnover stage provides for transferring each cigarette in the first succession from a first position in relation to the cigarettes in the second succession, to a second position on the opposite side of the cigarettes in the second succession as compared with the first position and a given distance from the cigarettes in the second succession; said transfer involving turning each cigarette in the first succession over by 180°, to form two successions of equioriented, transversely-spaced cigarettes.
- According to a preferred embodiment of the above method, the two successions of equioriented cigarettes are fed along respective separate paths to respective outputs of the filter assembly machine.
- The present invention also relates to a machine for producing filter-tipped cigarettes.
- According to the present invention, there is provided a machine for producing filter-tipped cigarettes, the machine comprising first feeding means for feeding two side by side successions of oppositely-oriented filter-tipped cigarettes; turnover means for turning over the cigarettes in a first of the two successions so that they are oriented the same way as the cigarettes in a second of the two successions; and second feeding means for feeding said two successions of equioriented cigarettes; characterized in that said turnover means comprise transfer means for transferring each cigarette in the first succession, by turning it over by 180°, from a first position in relation to the cigarettes in the second succession, to a second position on the opposite side of the cigarettes in the second succession as compared with the first position and a given distance from the cigarettes in the second succession, to form two successions of equioriented, transversely-spaced cigarettes.
- Said turnover means preferably also comprise a first and second roller with a common axis; the first roller being substantially twice as long as the second roller, and presenting seats for each receiving two oppositely-oriented cigarettes substantially contacting each other; and the second roller being located said given distance from the first roller, presenting seats for each receiving a respective cigarette, and being connected to the first roller by said transfer means.
- A number of non-limiting embodiments of the present invention will be described by way of example with reference to the accompanying drawings, in which:
- Figure 1 shows a schematic view in perspective, with parts removed for clarity, of a first preferred embodiment of a machine in accordance with the present invention;
- Figure 2 shows a larger-scale side view of a detail of the Figure 1 machine;
- Figure 3 shows a schematic view in perspective, with parts removed for clarity, of a second preferred embodiment of a machine in accordance with the present invention;
- Figure 4 shows a larger-scale plan view of a detail of the Figure 3 machine in two operating positions and an intermediate transition position.
- Number 1 in Figure 1 indicates a system for producing tobacco items and comprising a
filter assembly machine 2; and apacking assembly 3 presenting twoparallel packing lines input feed devices 6 and 7 spaced transversely in relation tolines - In known manner,
lines respective channels devices 6 and 7, for feedingrespective masses 10 of filter-tippedcigarettes 11 to respective feedboxes (not shown) supplying respective known conveyors (not shown). - Again with reference to Figure 1,
filter assembly machine 2 presents an output portion 12 supported on a single fixed frame (not shown), and comprising afirst roller 13 to which is fed, by means of twotransfer rollers double cigarettes 16, each comprising twocigarette portions double filter 19.Double cigarettes 16 are fed byroller 13, rotating clockwise in Figure 1, through a knowncutting station 20 where they are cut in half to form twosuccessions cigarettes 11, respectively indicated 11a and 11b, arranged side by side and oppositely oriented, i.e. with theirfilters 23 facing and substantially contacting each other. -
Successions roller 13 to aturnover unit 24 comprising two side byside rollers Roller 25 is tangent toroller 13; is substantially twice as long asroller 26; rotates anticlockwise in Figure 1 about its axis 27 (Figure 2); and presents a number of equally spacedperipheral suction seats 28 for each receiving and retaining arespective cigarette 11a and arespective cigarette 11b arranged facing, contacting, and oppositely oriented in relation to each other. -
Roller 26 is connected integral and coaxially withroller 25, on the same side assuccession 22, by ashaft 29 of given length, and presents a number of peripheral suction seats 30 (Figure 2), each extending in line and coaxially with acorresponding seat 28, and each designed to receive and retain a respective filter-tippedcigarette 11a parallel to and coaxial with acorresponding cigarette 11b housed incorresponding seat 28. As they travel aboutroller 25,cigarettes 11a insuccession 21 are fed to apickup station 31 where, by means of aturnover assembly 32 with conical rollers and forming part ofunit 24, they are withdrawn successively and turned over by 180° intoseats 30 onroller 26. Eachcigarette 11a insuccession 21 housed inside arespective seat 28 is thus turned over onto the opposite side ofsuccession 22 and positioned in line with and facing the same way as acorresponding cigarette 11b. - In the example shown,
assembly 32 comprises twoconical rollers axis 27.Roller 33 rotates clockwise in Figure 2 about itsaxis 35, and is tangent toroller 25 atstation 31 where the contacting generating lines ofrollers axis 27 and lie in a vertical plane parallel to the Figure 2 plane and containingaxes Roller 33 provides for withdrawing arespective cigarette 11a from aloading seat 28a instation 31, and presents a number ofperipheral suction seats 36 parallel to the generating lines ofroller 33, and each designed to receive and retain arespective cigarette 11a. -
Roller 34 rotates about anaxis 37 perpendicular toaxis 35 and lying in said verticalplane containing axes peripheral suction seats 38 parallel to the generating lines ofroller 34, and each designed to receive and retain arespective cigarette 11a.Roller 34 is tangent toroller 33 at atransfer station 34a where the contacting generating lines ofrollers axis 27 and coplanar with said verticalplane containing axes Roller 34 is also tangent toroller 26 at anunloading station 39 where the contacting generating lines ofrollers rollers station 31, and also lie in said verticalplane containing axes station 39,roller 34 provides for feeding arespective cigarette 11a into an unloadingseat 30a onroller 26, coaxial withseat 28a instation 39. - On leaving
unit 24,successions rollers respective rollers 40 arranged side by side and integral with each other, separated by a distance equal to the length ofshaft 29, respectively tangent torollers respective lines 41 and 42 for feedingrespective successions input devices 6 and 7 oflines assembly 3. - Each
line 41, 42 comprises twoconveyor rollers roller 43 is also tangent to arespective roller 40. Eachline 41, 42 also comprises, in known manner, a knowntest unit 45 in turn comprising aroller 46 tangent torespective roller 44 and which provides for feedingrespective cigarettes 11 to knowntest devices 47 for successively testing the permeability and/or integrity and/or ventilation ofcigarettes 11 and, if necessary, rejecting them at a known reject station (not shown) along the periphery of aroller 48 tangent toroller 46 and interposed betweenroller 46 and anoutput roller 49 cooperating with arespective input device 6, 7. - In connection with the above, it should be pointed out that, even if
machine 2 were to present a single output, andsuccessions turnover unit 24 would still be required due to the presence oftest unit 45 in whichsuccessions devices 47. - In actual use, on leaving
cutting station 20,cigarettes 11 are transferred toroller 25 and fed intoseats 28 in the original position, i.e. oppositely-oriented and coaxial, withfilters 23 substantially contacting each other. As it rotates,roller 25transfers cigarettes 11b insuccession 22 directly ontorespective roller 40, whereascigarettes 11a insuccession 21 are fed byroller 25 tostation 31 where they are withdrawn successively fromrespective seats 28 byturnover assembly 32, and turned over, by 180° in relation to the original position, intoseats 30 onroller 26.Roller 26 in turn transferscigarettes 11a insuccession 21 torespective roller 40, from which point on, theequioriented cigarettes 11 in bothsuccessions input devices 6 and 7 ofassembly 3. -
Successions equioriented cigarettes 11 are thus formed in an extremely straightforward manner, as of a knownfilter assembly machine 2, and using aturnover unit 24 whereby thecigarettes 11 in one ofsuccessions case succession 22, are fed, with no manipulation whatsoever, along a given path; while thecigarettes 11 in the other succession, in thiscase succession 21, are turned over by 180° and spaced in relation tocigarettes 11 insuccession 22 by feeding them along a semi-annular path defined by conical-roller turnover assembly 32. Moreover, by virtue of simply comprising two conical rollers,turnover assembly 32 is in itself extremely straightforward to produce and, hence, highly reliable, while at the same time providing for both equiorienting and axially spacing the cigarettes. - In connection with the spacing of
successions rollers rollers shaft 29 connecting the two rollers. - A further point to note in connection with the spacing of
successions unit 24 is of no great importance in that, assuming it is other than zero, it may easily be adjusted by means of straightforward known guide devices (not shown) comprising guide channels or wedges connected, for example, torollers cigarettes 11 axially and sopositioning successions input devices 6 and 7 ofassembly 3. - A further point to note is that, as a consequence of
succession 21 being turned over by 180° byturnover unit 24, the cigarettes at the output ofmachine 2 are oriented with the filter in view, i.e. with the filter facing the operator in front ofmachine 2. - Conversely, if
cigarettes 11b insuccession 22 were to be turned over, as opposed tocigarettes 11a insuccession 21, the cigarettes at the output ofmachine 2 would obviously all be oriented with the tobacco in view. To enable selection of the final orientation of the cigarettes at the output,machine 2 may be modified as shown in Figures 3 and 4 which relate to amachine 51 enabling the final orientation of the cigarettes to be selected, and the corresponding component parts of which are indicated, wherever possible, using the same numbering system as formachine 2. - As shown in Figure 3,
machine 51 comprises aframe 52 consisting of threeportions machine 2 wherein output portion 12 is supported, as stated, on a single fixed frame (not shown). More specifically,portion 53 is fixed and extends along the whole ofmachine 51, while the other two portions are fitted toportion 53 and movable in relation to it indirection 56 parallel toaxis 27. - Again with reference to Figure 3,
fixed portion 53 directly supportsrollers machine 51 upstream fromrollers portion 54 supportsunit 24, and is connected toportion 53 via the interposition of alinear actuator 57 for movingportion 54, indirection 56, between a withdrawn position (Figure 3) and an extracted position (Figures 4b, 4c). -
Unit 24 ofmachine 51 is substantially the same as that ofmachine 2, except that, as opposed toroller 25, it comprises twocoaxial rollers roller 26. More specifically,rollers shaft 29; whereasroller 58, betweenrollers shaft 29 by means of asplined coupling 60, so that it is movable, manually or by means of a known actuator (not shown), between a forward position (Figure 4a) whereinroller 58 is adjacent toroller 59 with which it defines a double roller similar toroller 25, and a withdrawn position (Figure 4c) whereinroller 58 is adjacent toroller 26 with which it defines a double roller also similar toroller 25.Roller 58 is locked selectively in the above two positions in known manner by means of lock pins (not shown). -
Portion 55 supportsrollers 40 and the whole ofmachine 51 downstream fromrollers 40 in the traveling direction of the cigarettes, and is connected toportion 53 via the interposition of alinear actuator 61 for movingportion 55, indirection 56, between a withdrawn position (Figure 3) and a forward position (Figures 4b, 4c). -
Machine 51 may thus assume two terminal operating configurations, a first as shown in Figures 3 and 4a and corresponding to the configuration ofmachine 2, and a second as shown in Figure 4c. - With reference to Figure 4, passage from the first to the second of the above configurations is effected (Figure 4b) by operating
